it exhibits the same jagged edges/lines as what I'm seeing on my set, my laserdisc player is a Pioneer CLD-D515, capturing with a Canopus ADVC-100, I get the same jaggies if I capture with my Matrox G450 gfx/tv card (see back a few posts). None of the other 30 or so NTSC laserdiscs I have exhibit the same jaggies as the SW definitive set.
Can you post the same still from your capture of the definitive set?
